An autopsy performed on Tuesday determined that 55-year-old Caren Archer, of McDonough, died of a self-inflicted gunshot wound to the chest at a Delta Air Lines facility at Atlanta's airport, according to a public information officer for the Georgia Bureau of Investigation (GBI).

John Bankhead said the autopsy results were consistent with the evidence that was found inside Archer's vehicle. "The investigation into this incident is still continuing," said Bankhead, in a written statement.

According to Bankhead, several parties at the Delta Technical Operations Center were made aware that Archer was carrying a weapon and making threats against her husband, who works at the center.

The woman [Archer] had a handgun in her possession, said Lt. Tina Daniel, a public information officer with the Clayton County Police Department.

Archer's husband was not at work when the incident occurred, according to Daniel. She said it is unclear how the woman was able to get through the center's gate with her vehicle.

The police department received a call about the incident at approximately 1:30 p.m., Monday, said Daniel. The incident occurred at the operations center, located at 1775 Aviation Blvd., in Atlanta, she said.

Lt. Daniel said shots were allegedly fired by two parties. She said she could not give further information about the parties involved, due to a pending investigation.

Shots were exchanged in an officer-involved shooting, "in a standard operating procedure," according to Daniel, who said she could not elaborate on the details of the shooting. "All we can say is [it is] possible family violence," said Daniel about the incident.

According to Bankhead, Archer was inside her vehicle and a police officer was standing outside. Archer pulled out her weapon [apparently to shoot herself], said Bankhead, during a phone interview. "He [the officer] apparently thought she was shooting at him, so he shot at the vehicle," said Bankhead. "She was in the vehicle."

Bankhead said the GBI took the case over from the Clayton County Police Department, because an officer was involved in a shooting. The GBI served as an outside agency to investigate the case, he said.

"We were requested by Clayton County," added Bankhead.

The incident did not affect operations at Hartsfield-Jackson Atlanta International Airport, Daniel added.

The Clayton County Police Department was contacted on Tuesday, and asked to elaborate further on the case. Officer Otis Willis, III, another public information officer for the department, said he was unable to disclose any further information, because of the ongoing investigation.
